Abstract

Human papillomavirus (HPV) type 58 is a high-risk type of HPV frequently detected in cervical cancers, especially in Eastern Asia. There are still no commercially available vaccines against HPV 58 infection. High levels of long-lasting neutralizing antibodies are crucial for long-term protection against HPV infection. Here, we have developed a two-step chromatography strategy and have purified highly pure HPV L1 proteins, which form more homogenous and uniform VLPs than those purified by CsCl ultracentrifugation. Low-dosage immunization with HPV 58 L1 VLPs alone or co-administrated with HPV 16 and HPV 18 L1 VLPs is sufficient to induce high levels of long-lasting neutralizing antibodies in mice. Our results suggest that the highly immunogenic HPV 58 L1 VLPs are a good candidate for use in developing effective vaccines against HPV 58 infection.
